摘要
文章以长春市的城市规划、不同道路特征、不同路段的交通流特性等因素为依据,选取具有代表性典型路段,即主干线306路为调查样本进行取样试验;依据严寒及寒冷地区分类的国家标准,确定冬季试验时间为2013年1月;通过公共汽车的行驶条件确定试验方法为平均车流法;所用试验车辆为中国第一汽车集团公司所产的解放牌CA6120URH2型公共汽车。试验将采集到的数据根据不同行驶状态划分为若干行程片段,并分别计算出每个片段的对应特征值,进而对所有数据片段进行了主成分分析和聚类分析,在相关性及有效性验证之后通过数据拟合构建成主干路典型行驶工况。
In this paper,we make one typical road to be the survey samples in Changchun;It is Line 306.We have got many different types of data by using reasonable statistical methods and equipment. We made the data to be many stroke segments and calculated the eigenvalues of each segment by using the software.And then we made the principal component analysis and cluster analysis of the segments by using SPSS. At last, we made the speed-time joint distribution curve of the road with the fitting data after the correlation verification and validation.
